The perimeter of an equilateral triangle is 18p - 24. Write an expression to represent the length of each side.

grandymaker [24]

Answer:

6p -8

Step-by-step explanation:

The three sides of an equilateral triangle are all the same length. (This is the literal meaning of "equilateral.") So, the length of one side is 1/3 the total length.

each side = $\dfrac{18p-24}{3}=\dfrac{18p}{3}-\dfrac{24}{3}=6p-8$

Question 4 Please help. If circle A is dilated so that it is the same size as circle B, which transformations could be performed

DIA [1.3K]

There are 3 Answers:

Choice A) reflect the dilated circle over the horizontal line through point C.

Choice D) rotate the dilated circle 180 degrees around point C

Choice E) translate the dilated circle to center B

Due to symmetry, rotations and reflections do not change a circle. This is why we are able to rotate around point C so that it looks like a translation has occurred. A similar thing happens with reflections as well.
